this is always cited as the "killer functionality" of venti. essentially it trades cpu time for disk space. however, the couple of times where a concrete venti solution was discussed (seperating attachments into seperate files, e.g. for de-duping), it was deemed to be slower because attachments need to be split out to be recognized as the same. (9fans.net/archive/2005/10 and 9fans.net/archive/2005/11/1). i wonder about this today with such large disks. does anyone have an example of a case where compression and uniquing are required? - erik
